The knowledge about natural oral esthetics and the interactive relationship between patient-clinician-technician constitute the basic strategies for successful esthetic rehabilitations.

Study models and diagnostic wax ups, as well as mock-ups and provisional restorations represent a key element in the realization of esthetic rehabilitations. In particular, they provide indispensable diagnostic information, they contribute significantly to adjacent soft tissue conditioning, and they assure the patient's subjective comfort during this intermediate phase of treatment.

The treatment outcome strongly depends on the therapeutic approach chosen. This lecture describes a treatment rationale that comprises the use of a diagnostic template. This type of work strategy, documented with clinical cases, integrates diagnostic wax-ups, mockups and indirect provisionals using simplified and efficient fabrication techniques to secure the way to achieve ultimate aesthetics with the final bonded porcelaine restoration.
